GRAIN- SPECIFICATION forming part of Letters Patent No. 654,057, dated July 17, 1900.

Application filed O o 12. 1899. Serial No. 733,444. (No model.)

To all whom it mrry concern:

- Be it known that 1, CHARLES L. FowLE, a eitizen of the United States, residing at the ieity of Dowagiac, in thecounty of Cass and 5 State of Michigan, have invented certain new I and useful Improvements in Grain-Drills, of

which the following is a specification.

This invention relates to improvements in force-feed seeding apparatus for grain-drills.

10 The object of this invention is to provide an improved construction of force-feed for grain-drills which shall secure a more even and satisfactory flow of the seed from the hopper to the drill below.

1 5 l. accomplish the object of my invention by the structure described in the following specification. The invention is clearly defined and pointed out in the claims.

The structure to which my invention per- 20 tains is clearly illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a detail view of a seed-cup and feed mechanism, partially in section, on a Fig. 2 is a transverse detail sectional view taken on a line corresponding to line 2 2 of Fig. 1. Fig. s a detail perspective view of the rosette-washer with my invention applied.

3:) In the drawings the sectional views are taken locking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

5 Referring to the lettered parts of the drawings, A represents the bottom board of the hopper. A represents the seed-cup, secured to the under side thereof, the same being made, prcferably,in two parts suitably riveted Extending transversely through this seed-cu p is the shaft B, bearing the fluted feed-cylinder D, and a cylinder or sleeve 0, bearing suitable gates C C for shutting off the outlet from the seed- 5 cup and regulating the discharge-passage.

The shaft B is prefcrabl y square, fitting into a square hole in the fluted feed-cylinder D, so as to revolve the same. A suitable bushing is put into the sleeve C, so that the shaft re- The sleeve C and the fluted feed-roll are held in contact with eaclrother by means of the spring F. The shaft extends the entire length of the hopper of the drill, and being controlled by suitableconnections regulates the position of the sleeve C, with its gates C' C", and so controls the amount of seed sown. The fluted feedcylinder D fits within a revoluble rosettewasher E, so that it slides freely back and forth through the sane. This is supported in the side of the seed-cup. The washer has an in wardly-projecting rim E, and opposite each flute or groove in the seed-roll is a projecting lug E. From this it will be seen that when the shaft B is rotated in the proper direction it rotates the feed-roll D and also the rosettewasher E, and the projecting lugs E slightly agitate the grain within the cup, so that it will flow more freely and at the same time engage against the kernels and carry them out at the discharge or opening more freely and evenly than they otherwise would, and,

in fact, secures the most even distribution and feeding of grain from the feed-hopper that it has been possible to attain up to the present time.

I have described the shaft 13 as square. It could be of anyother irregular form in crosssection, so long as it effectually engages the feed-roll. In fact, other means might be provided of actuating the feed-roll, so long as it is possible to adjust it back and forth into the seed-cu p.

Other styles of gate might be employed for restricting the outlet-passage from the seedcup. I have shown thesame' in the preferred form.

From these statements it will be readily understood that the structure is capable of considerable variation without departing from my invention. 7

Having thus described nlyinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a force-feed, the combination of a seed-cup; a fluted force-feed seed wheel or roller; 3. rosette-washer supported in one side of the cup, fitting said seed wheel or roller, the said washer having its. outer edge inwardly turned and provided with lugs opposite the flutes of the seed-wheel, all coaeting for the purpose specified.

2. In a force-feed the combination of a seed-cup; a force-feed seed wheel or roller; awasher supported in one side of the cup iii.- ting said seed wheeler ruiler, the anal washer having its outer edge inwardly turned, and provided with lugs to agitate and carry the seed forward, for the purpose specified.

3. In a f0rcefeed, the combination of a feed wheel or roller; a washer iitied to the same, having an inwardly-turned rim, with lugs thereon to assist'in agiini-ing and discharging, as specified.

i. In a force-feed, the combination of a feed wheel or roller; a washer fitted t0 the same, with laterally-exlending lugs at the periphery only and tapering toward the menter to assist in agitating and discharging, as specified.

In Witness whereof I have hereunio set my hand and seal in the presence of two witnesses.
